The RTX 5070 loses its edge once OEMs cap TGP — often no better than a 5060

When laptop makers turn down the juice, the RTX 5070’s advantage evaporates

Buy a laptop because it lists an “RTX 5070” sticker and you’re paying for potential – not the guaranteed result. GameStar’s TGP checks make that brutal truth concrete: under the reduced power envelopes common in thin-and-light machines the 5070 often matches or trails a cheaper RTX 5060, and at 50 W it collapses entirely.

• Real headline: a 5070 on a 75 W TGP is usually no faster than a 5060 at 100 W; at 50 W the 5070 falls behind badly.
• Why it matters: OEM power limits – not the chip name – decide in-laptop performance. Paying more for a 5070 can be a net loss unless you confirm the laptop’s TGP or buy the Ti.
• Quick decision rule: if you can’t get a 5070 Ti or a 5060 in a higher‑TGP configuration, assume the standard 5070 will underdeliver.

GameStar’s test: exact numbers you can’t ignore

GameStar ran the RTX 5070 on XMG test rigs (AMD Ryzen AI 9 HX 370, 32 GB DDR5, RTX 5070 8 GB GDDR7), with Dynamic Boost off and maximum in-game settings but no ray tracing or upscaling. They compared full-TGP, 75 W and 50 W states versus an RTX 5060 operating at 100 W. The results are stark and consistent across three modern hits.

• Cyberpunk 2077 (FHD): full TGP: 5070 only ~6% faster than 5060; at 75 W it’s essentially equal to a 5060 (100 W); at 50 W the 5070 drops ~29% from full TGP and sits ~21% slower than the 5060 (100 W).
• Cyberpunk (QHD): the 5070 loses ~9% at 75 W and ~32% at 50 W versus its full-TGP numbers — practically indistinguishable from a 5060.
• Assassin’s Creed Valhalla: in FHD the 5070’s drop from TGP scaling is 7-23%; QHD shows the 5070 just ~6% ahead of the 5060, but at 50 W it loses ~26% of its performance.
• Assassin’s Creed Shadows: the one title where the 5070 shows a lead (~17%) at full TGP — but at 75 W it loses ~7%, and at 50 W it collapses ~26%; moving to QHD the drop balloons to ~38%.

Why the chip name is misleading for laptop shoppers

GPU model numbers are marketing shorthand. The on-paper leap from 5060 to 5070 assumes both chips can run at similar power budgets. In real laptops, chassis design, cooling cost targets and battery-life priorities force OEMs to pick a TGP — often 75 W or lower for thin machines. A 5070 constrained to 75 W often performs like a 5060 at 100 W. At 50 W it’s a nonstarter.

That’s the uncomfortable observation the PR decks hope you miss: it’s not enough to read “RTX 5070” on a spec sheet. You need the TGP number, and you need to check how many watts the OEM actually configures. Otherwise you’re buying a label, not performance.

The other shoe: 8 GB VRAM is already borderline

GameStar also flagged a secondary problem: the standard 5070 ships with 8 GB of GDDR7. That’s getting tight for modern open-world titles at high settings and higher resolutions. Even if a laptop runs the 5070 at full TGP, 8 GB limits future‑proofing — another reason to prefer a 5070 Ti (more VRAM) or ensure a 5060 is on a higher TGP.

The question nobody from marketing wants to answer

If OEMs will frequently ship the 5070 at 75 W or lower, why push the SKU at all? The real question I’d ask Nvidia and laptop makers: are you selling meaningful generational upgrades or simply chasing higher part‑numbers on spec sheets? Because consumers pay premiums based on model names — not on the watts set under the hood.

What to watch next — concrete checks before you buy

• Always verify the laptop’s listed GPU TGP (in watts). If the seller doesn’t state it, assume the card is configured conservatively.
• Prefer RTX 5070 Ti or an RTX 5060 in a confirmed 100 W+ configuration over a standard 5070 at 75 W or less.
• Look for 12 GB+ VRAM if you plan to play open-world or future titles at QHD or high textures.
• Benchmarks that match your target resolution (FHD vs QHD) — the 5070’s advantage erodes fastest at higher resolutions.
• Fun aside: Cyberpunk 2077, one of the test games, is now on Xbox Game Pass for consoles/cloud from March 10 — handy if you want to try the game but irrelevant to PC laptop benchmarking unless you own it.

My read: the vanilla RTX 5070 is a fragile promise. In laptops that prioritize thinness or battery life — which is most of the market — that promise is often broken. Spend the premium only if you can confirm the laptop’s TGP or you can step up to the 5070 Ti. Otherwise, a higher‑TGP 5060 will give you more consistent, predictable performance for less money.

TL;DR

GameStar’s benchmarks show the RTX 5070 frequently loses to a 5060 once OEMs cap its TGP. 75 W commonly equals a 5060 (100 W); 50 W is a performance sink. Check TGP and VRAM before paying extra — or just buy the 5070 Ti or a higher‑TGP 5060.
